This lively text offers a unique, holistic approach to human diversity for undergraduate courses in fields including anthropology, medicine, human ecology, and general education. Leading medical anthropologist Elisa Sobo rises to the challenge of truly integrating biology and culture. Her inviting writing style and fascinating examples make important new ideas from complexity theory and epigenetics accessible to undergraduates from all disciplines, regardless of academic background. Students learn to conceptualize human biology and culture concurrently-as an adaptive biocultural capacity that has helped to produce the rich range of human diversity seen today. With clearly structured topics, an extensive glossary and suggestions for further reading, this text makes a complex, interdisciplinary topic a joy to teach.
